Explanation:
Get out your red/blue glasses and gaze across Ceres at
mysterious
mountain Ahuna Mons.
Shown in a 3D anaglyph
perspective view, the mosaicked
image data was captured in December of 2015, taken from the
Dawn spacecraft's low-altitude mapping orbit
about 385 kilometers above the surface of the dwarf planet.
A remarkable dome-shaped feature on Ceres,
with steep, smooth sides Ahuna Mons
is about 20 kilometers (12 miles) in diameter at its base,
rising on average 4 kilometers to a flattened summit.
Similar in size
to mountains found on planet Earth, no other
Cerean surface
feature is so tall and well-defined.
It is not known what process shaped the lonely Ahuna Mons,
or if the bright material streaking its steepest side is
the same material responsible for Ceres'
famous bright spots.
